PULLEY.

SPECIFICATION forming part of I ietters PatentNo. 295,698, dated March25, 18184.

A pplication tiled February 5, 1884. (No model.) 'D I To a/ZZ whom t mayconcern:

Be it known that we, JULIUs E. WArERoUs and JAMES N. PEEL,- subjects ofthe Queen of Great Britain, both residing at Brantford, in4

which will be hereinafter fully set forth, and pointed out in theclaims.

In the accompanying drawings, consisting of two sheets, Figure lis aside elevation of our improved pulley. Fig. 2 is a section in line .frw, Fig. l. Fig. 3 is a sectional eleva tion of the outer edge of one ofthe arms and connecting parts. Fig. 4 isa plan view of the arm-head.Figs. 5 and 6 aresectional elevations of modiiied constructions of themeans whereby the arms are secured to the rim.

Like letters of reference indicate like parts in the several iigures.

A represents the hub of the pulley; B, the arms, and C the rim. The armsB are constructed of wrought-iron or steel, and flattened or otherwiseenlarged at their inner ends, as represented in Fig. 2, so that uponplacing the inner ends of the arms in the moldV of the hub and castingthe latter on the arms the latter will be iirmly secured to the hub. Thearms may be secured in the hub by keys or other suitable means; but weprefer to cast them in the hub, as it makes a simpler and 'strongerconnection.

D represents the arm-heads, which are attached to the outer ends of thearms and secured to the inner side of the rim. The heads D are madehollow, and iit with their open outer ends against the inner side of therim C. Each head is provided with projecting ears d, which are securedto the same by rivets cl.

As represented in Figs. l, 2, and 3, the outer end of each arm isprovided with an external screwthread, e, which engages in aninternally-threaded sleeve, E, seatedin a bore of thehead D, andprovided at its outer end with a flange, j', which engages against ashoulder, f', at the bottom of the cavity G of the head D.

H represents a jam nut. applied to the threaded end of the arm, andbearing against the inner end of the sleeve E. The inner end of thesleeve E, which projects beyond the bore of the head D,'is madehexagonal, or otherwise constructed so that the sleeve can be turned bya winch. When the arms B have been cast in the hub A, the heads D andsleeves E are applied to the outer ends of the arms and adjusted withreference to the axis of the pulley. The rim Gis then riveted to theheads D, whereby the pulley is completed. If the speed ofthe pulley isso high that the l centrifugal force will cause a considerable outwardpressure on the arms, this pressureis compensated for by adjusting thesleeves E inwardly until a sufficient inward pressure is applied to therim and arms to balance the outward pressure produced by the centrifugalforce..- If the pulley is not balanced when the rim has been applied,holesi are drilled through the rim opposite one or more of the cavitiesG of the heads D, on the light side of the pulley, and the cavities Gare filled with molten lead or other suitable metal until balanced.

In the construction represented in Fig. 5`

H on the inner side of the sleeve, anda jam' nut, H', applied to the armB in the cavity of the sleeve, between the latter and the inne` end ofthe head D. A

In the construction represented in Fig.. 6 the threaded outer end of thearm B is screwed directly into the threaded opening of the head D andlocked by the jam-nut H. The arms B are preferably made tapering fromthe hub toward `the rim, to render them light and strong.

The rim may be constructed of one or more the pulley is IOO parts,according to the size of the pulleys, and the arm-heads D, which areapplied to the joints of the rim, are arranged with their ears d atright angles to the joint, to firmly connect the ends of therim-sections, as represented at j in Fig. l. The edges of therinrsections are further secured together by strips k, riveted to theinner sides of the rim.

We claim as our invention- 1. The combination, With the hub A, of armsB, rigidly secured thereto, adjustable heads D, applied tothe outer endsof the arms, and a rim, G, secured tothe heads D, substantially as setforth.

2. The combination; with the. hub A, of arms B, rigidly secured thereto,heads D, arranged at the outer ends of the arms, sleeves E, whereby theheads D are adj ustably secured to the arms, and a rim, C, secured tothe heads D, substantially as set forth.

3. The combination, with the hub A and rim C, of arms B, rigidly securedto the hub, and having their outer ends provided -with externalscrew-threads, heads D, secured to the inner side of the rim, andsleeves E, constructed 'with internal screwthreads, and having flangesfat their outer ends bearing against the sleeves,

substantially as set forth.

4L. The combination, With the hub A, arms B, and rim C, of heads D,connecting the rim to the arms, and constructed with cavities adapted toreceive counterbalancing material, substantially as set forth.

Vitness our hands this 31st day of January, 1884.
